I trying to choose a highly intensive sport. Im stuck between Choy Li Fut Kung Fu and Muai Thai Kickboxing. I like that Choy Li Fut focuses on some takedowns and grappling but I hear Muai Thai is extremely effective as a self defense on the street. How effective is Choy Li Fut on the street? Im black belt, former state champion (about 10 years ago as I no longer practice) and qualified for the junior olympics in traditional Korean Tae Kwon Do and but havent found it to be reliably effective on the street as its more of a sport/self dicipline/lifestyle than it is a hardcore self defence style. Thats what I really want…a hardcore self defense style. My job requires me to go into bad neighborhoods alone at night & I have a wife at home so I need to be prepared to make an effective attempt at incapacitating an agressor. Do you think Choy Li Fut is hardcore enough for me? I want some seriously hardcore stuff.
